I think Kevin Casey might have some health issues, as he said. Before anyone else accuses him of "not having a strong enough will," just remember that health problems can happen to anybody, and it's inevitable that sometimes a fighter is going to have health issues come up in the middle of a fight. We can't expect people to keep fighting if they're having serious debilitating problems, and it's the smart thing to do if you think you have no chance of winning and a big chance of getting hurt. Of course, sometimes maybe people quit when they probably shouldn't, but that's the exception rather than the rule.

kevin casey isnt really a fighter, he's a wrestler.
in both his match-ups, he didnt fight, just wrestled. its almost like he is afraid to punch or be punched.
you would think that a guy with his physique would be quite a monster, yet he is quite the opposite when it comes to fight time.
dont get me wrong, i couldnt get in the cage to do this, but he is meant to be an ultimate fighter,
